Browser Extensions:

"Different browsers have different extension systems. Firefox has the most powerful one. Many people use Firefox because of this — Firefox makes many advanced extensions possible that wouldn’t be possible on other browsers. Because of its history, even extensions that would be possible in another browser may only be available for Firefox.

Chrome also has a thriving extension ecosystem and there’s probably also a Chrome extension for most everything you’d want to do. Chrome places more limits on its browser extensions so they can’t be quite as powerful as they are in Firefox, but these limits allow Chrome to present a permissions system and restrict extensions a bit more for security.

Internet Explorer has a very small add-on ecosystem. Few add-ons are available, and most of the Internet Explorer add-ons in actual use are probably browser toolbars like the terrible Ask toolbar that were foisted on users through bundling with other software. If you want add-ons, Internet Explorer is not the browser to use.

Safari and Opera also have extensions available, but their ecosystems are much smaller than Firefox’s and Chrome’s."

Browser Plug-ins:

"Note that extensions, or add-ons, aren’t the same as browser plug-ins. “Plug-ins” are things like Adobe Flash, Oracle Java, or Microsoft Silverlight. They allow websites to embed and render content — Flash movies, PDFs, or Java applets, for example — that are rendered with the plug-in... Essentially, extensions add features you can use, while plug-ins add features websites can use."
